.BOLT. GUIDE. 7

This invention relates, to sliding boltsfor securing or looking doors, casement windows, and the like in closed position.

More particularly, the invention resides in a guide or staple for slidablysupporting the bolt.

An aim ofthe invention islto provide a staple' o'f this character which is :very neat and trim in appearance. LMy improved staple is relatively narrow, being onlyslight- 1y widerfthan the bolt which it supports and i The,

' which secure the staple in place hold the staple in proper formed condition.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construct-ion hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawings:

Figure 1 is a View of a pair of my improved staples supporting a bolt;

Fig. 2 is a transverse sectional View taken on line 22 of Fig. 1;

Fig. 3 is a top view of my improved staple;

Fig. 4 is a bottom view thereof;

Iiig. 5 is a perspective view of the staple; an

Fig. 6 is a View of a blank from which the staple is constructed. 7

Referring to the drawings in detail, a denotes a bolt of suitable construction; 6, my improved guides or staples for slidably supporting the bolt; and 0, the usual strike plate. The bolt may be carried by a door or the sash of a casement window or the like, and the strike plate is carried by the casing 2, 1926. Serial No. 85,552.

orframe in theusual manner. The bolt, in the present illustrative disclosure, is half round incross section, that is tosay, semicylindrical, V i I Referring now more particularly to my improved guide, the same has an elongated base portion-10, an car 11 at each end of t he base portion, and a bridge portion;12 curved correspondingly to the curved surface of the bolt. The bridge or arch arises .froni and is formed integral with, the side edges of the,

base. The ears 11 may be provided with openings 13 to receive fastening n1eans, such as screws l4, and which screws, when the bolt is in place, are concealed bythebolt. The base is diagonally slit, as at 15, one ear being joined to the metalto .oneside of this slit, and the other being joined to the metal to the other side of the slit.

My improvedv guide may be formed from a blanklof sheet metal, such as shown in ig. 6. This blankmay be stamped to the configuration shown, and has ;an. intermediate port-ion 12 which, when the blank is bent to form, constitutes an arch. At opposite sides of this intermediate portion are oppositely disposed triangular portions 10 which are adapted to form the'base 10. The edges 15 of the portions 10 are in parallelism with each other so that, when the blank is bent into semi-circular shape, these edges meet to form the slit 15. At diametrically opposite corners of the blank are the ears 11 which, preferably, project, as at 17 slightly beyond the inclined edges 15. i

It will be noted from the foregoing description, taken in connection with the ac companying drawings, that my improved guide or staple may be manufactured at a .very low cost, since the staple is constructed of sheet metal and but two operations, each of which may be cheaply carried out, are necessary in constructing the staple, these 0 erations being that of stamping from s eet metal a blank to the configuration shown in Fig. 6, and then rolling the blank into semi-cyclindrical form. In case the openings or holes 13 are to be countersunk, as shown, the countersinking operation may be very readily carried out. i

The completed staple is relatively narrow and, in fact, extends beyond the side edges of the bolt only that distance substantially equal to the thickness of the metal of which the blank is formed. The staple is substantially of uniform width throughout its length, and the screws 14 are positioned behind, and are obscured from View by, the bolt. This means that the staple is very sightly and trim, a feature of Considerable importance in hardware of this sort. The staple is very strong and rigid and, since the ears are respectively integral with the two portions of the base, and the slit 15 is diagonally disposed, the screws 14 maintain the staple against lateral spreading and distortion,

As many changes could be made in the above construction and many apparently widely different embodiments or this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

I claim as my invention:

1. A staple for sliding bolts formed of sheet metal and having a base with a slit, a single ear extending from each end of said base, and an arch arising from and formed integrally with the side edges of said base; i

one of said ears being'integral with the metal of the base to one side of said slit, and the other ear being integral with the metal of the base to the other side of said slit each of said ears being of substantially the same Width as the staple and extending longitudinally of the base.

2. A staple for sliding bolts formedfrom a blank of sheet metal rolled into semi-cylindrical shape and having a fiat base with an apertured ear at each end and a diagonally extending slit where the side edges of the rolled blank meet, and a semi-cylindrical arch integral with the side edges 01 said base between said ears each of said ears extending in the longitudinal direction of the staple and being within the limits of the side edges of the staple.

3. A staple for sliding bolts havinga flat base portion with an car at each end, and a bridge portion integral with the side edges of said base portion between said ears, said base portion having a slit extending d1ago nally substantially from one side edge to the other side edge thereof, said ears-being substantially as wide as said baseportion and being respectively integral with the metal to opposite sides of said slit, each of said ears extending longitudinally of the base and being within the limits of the sideedges of the base.
